Last month, Pete Wentz told MTV News that the next Fall Out Boy album will be so riff-heavy, it might sound like AC/DC. The bassist confirms to Rolling Stone that he and singer-guitarist Patrick Stump are working on new tracks this summer the way they usually do: “Patrick’s obviously been writing all the music, and the words haven’t even really come in yet,” Wentz says. “I’ll go over to Patrick’s house and he’ll kind of just sit there and play songs, and I’ll be like, ‘Ah, that one’s awesome!'”

So will Wentz’s lyrics reflect his new status as a new husband and expectant father? “I think that it’s kind of blown out of control,” he says. “That people expect us to have a happy fairy tale record or something.” He notes that the band wanted to get started on new music sooner, but their cover of Michael Jackson’s “Beat It” stood in the way. “I’m psyched to write new songs,” he says. “‘Beat It’ took off a little bit and that kind of stalled out our label and stuff like, ‘We gotta film a video for this.’ We weren’t in the right headspace to write songs before,” he adds. “We tried to before we went to Chile, and it makes a lot more sense now. We became good friends again, which is good.”
